LG 29EA93 Monitor Review - Rev. 1.25
by Chris Heinonen on February 12, 2013 8:49 PM ESTThe initial revision of the LG 29EA93 was very uniform overall, where I remarked, “For white uniformity, the 29EA93 is truly a cut above.” Despite this, LG was unhappy about the performance of the corners and went back and tightened the tolerances of assembling the screen to get better performance out of it. Unlike before, no areas drop below 180 cd/m² of light output, keeping the whole screen uniform within 10% when using the same 5x5 ANSI test pattern as before.
Light Output in cd/m2
Output Deviation Relative to Center
There are two points on the side that are slightly darker, in the same location as before, but the light loss in those areas is less than before. Overall the white uniformity manages to maintain its reputation of being great.
Black Uniformity is what had the issue before, with the corners having a lot more light creeping into the corners. This time that condition no longer exists. The only actual error that you can see is that one of the dimmer areas from the white uniformity is very dim in the black uniformity screen as well, but something being darker rather than lighter is a good thing.

Output Deviation Relative to Center
Now looking at contrast uniformity, we see the most impressive result for the 29EA93 yet. The average contrast value here is 1267:1, and the corners maintain a contrast level of 1252:1. This is now the best display I’ve seen in terms of contrast uniformity, with no areas of the screen that are a cause of concern to me at all. I really hope other manufacturers see what LG was able to do here with better quality control and bring that to their displays to provide similar results.
Contrast Ratio
Contrast Ratio Deviation Relative to Center
For dE uniformity, I used the Uniformity tool available in CalMAN that can measure up to 45 points on the screen. For this display I used 21 points, in a 7x3 grid, which was a perfect match to the 21:9 ratio of the screen. The Uniformity tool isn’t completely finished yet, which is why I didn’t use it for brightness yet, but the dE uniformity is close to what we used to do, only with more data. Once the Uniformity tool is finished it’ll provide even better data, and I can go back to this review and update the graphs to match.
As you can see the center of the screen has very good color quality that we saw earlier. The extreme corners exhibit a bit of color drift with dE values that are a little worse, but only the upper-right corner moves past the 3.0 value that would indicate a color change that we can see. In comparison to the contrast numbers the color quality is only very good, but as this is the first display to be tested this way, it wouldn’t surprise me if this is the best display we see for a while and this method only accentuates the errors.
Colorchecker dE Uniformity
The LG 29EA93 was already a very good performer when it came to uniformity, and the improvements that LG made only increase that performance. The extra attention paid to make sure that the assembly of the extra-wide panel is done right has served to produce the most uniform consumer display that I’ve seen so far.

I don't add calibrated settings for a reason: They're specific to that display, and that one only. The level of tolerances on a consumer panel is high enough that just plugging in the settings from someone is no guarantee that the image will be better or worse, just different. And since it can be just as easily worse as opposed to better, I don't provide them. Otherwise I know it will result in many people getting those settings from somewhere else, or without a disclaimer like this, using them, and then posting "The AnandTech settings made my display worse, they have no idea what they're talking about".If the display has a mode that is more accurate, I typically mention which one I used for calibration so everyone could use that specific mode, buy beyond that and adjustments are just as likely to make a display worse as better.

Don't bother with this monitor yet. There's no 1.25 version out there.Adrianojp - Tuesday, February 26, 2013 - link
Hi,This is my first post, but I have been reading your site for years now.
Thank you for all your great work!
Response times: in your 1.25 review, you state that RT's have been tested at 1080p resolution because of some CRT limitations. Could you please iron this out for me?
I am a hardcore FPS gamer, and am out shopping for the fastest 27-30 monitor out there! This would be very interesting because of it's huge landscape, but lag is a no no!

So I noticed that now Newegg and Microcenter are carrying this monitor. There's a guy on the HardOCP forums that bought one and is doing a review. The picture he took of the back shows a manufacturer date of January 2013, but a rev00. I know they weren't released in the US officially so for all I know rev00 is the 1.25 here, but seems kinda risky to buy without knowing for sure.carloverthepond - Tuesday, March 19, 2013 - link
I purchased this monitor from South Korea arrived with build date Dec 2012 Rev 00 shockingly poor panel over 30 stuck/dead/live pixels. This month I purchased one from Frys again build date Dec 2012 Rev 00, then one from MicroCenter yet again build date Dec 2012 Rev 00. The money I have lost in shipping and restocking fees is now a joke. Currently awaiting one I ordered from Newegg arrives 03/22/13 their website photos show build Feb 2013 Rev 01, so how do we know if this is revision 1.09 or 1.25. After several conversations with LG USA they posted the comment below on Neweggs website, how can you truly tell what revision you have when it's not labeled clearly and manufacturer just says it's revision 1.25 are we to take their word? If anyone has any idea how to identify which revision other than sticker on rear of panel? An LG USA have been very clear they will NOT update older revisions to their knowledge they don't even have the means to do so.Manufacturer Response:
1. The older version is neither defective nor low quality. It was just a running change to update the firmware
to newer versions (like is done with other electronics).
2. Currently, there hasn’t been any game resolution support issues reported for this model. Please contact us with
any issues you find so we can test. Our previous internal testing did not find any resolution support issues for
any games. Also, Software version is not related to resolution support and different versions do not effect ability
to support full 2560 x 1080 resolution.
3. All of models sold to newegg.com are firmware version 1.25.
Please call us with any more questions. 800-243-0000.

Received new monitor today from newegg and the manufatures response is incorrect, newegg are selling revision 00. So some people get the new revision and others like me yet again get the old one. This will now be my fifth monitor, will I ever get the new revision. Is it accurate that rev 00 is really 1.09 and rev 01 is 1.25?5150Joker - Saturday, March 23, 2013 - link
Your guess is as good as mine. I picked up an LG 27EA83-D from Fry's which just recently received a firmware update of its own with similar results as the panel you bought. However mine was manufactured in Jan 2013 and is Rev 00. I wrote LG USA about it and they had no clue (surprise surprise). So right now I'm trying to get a hold of someone in Korea that can provide firm answers. Otherwise as much as I love this display, it might go back to Fry's.rogerRion - Wednesday, March 27, 2013 - link
1.09 / 1.25what do i have?
the same in germany.
A) isnt there a way to find out which revision do you really have? maybe with powerstip on the DDC data?
B) is a simple Firmware Update (like on CDRW drives) possible, or is this thought technical not logical?
SpartanGR - Monday, April 1, 2013 - link
A. Unfortunately noB. No again for some reason but i strongly believe that it may well as be diff. electronics along with diff. firmware

How to know which Rev. you will buy in the shop?Anyone know how to find out?
